When you open the Task Manager on your Windows computer, you may notice a process called “Spooler SubSystem App” running in the background. This process, also known as spoolsv.exe, is an essential component of the Windows operating system that handles print jobs and manages the printing queue. In this article, we will explore why the Spooler SubSystem App process is running in Task Manager and its significance in the printing functionality of your computer.

Understanding the Spooler SubSystem App Process

The Spooler SubSystem App process, spoolsv.exe, is responsible for managing print jobs and ensuring they are sent to the correct printer. It acts as an intermediary between the application that sends the print job and the printer itself. When you print a document, the data is first sent to the spooler, which then processes the print job and sends it to the printer.

The spooler also manages the printing queue, allowing multiple print jobs to be queued and printed in the order they were received. This ensures that print jobs are processed efficiently and prevents conflicts when multiple users are trying to print simultaneously.

Why Is the Spooler SubSystem App Process Running?

The Spooler SubSystem App process is always running in the background on a Windows computer because it is necessary for the printing functionality to work properly. Even if you are not actively printing anything, the spooler needs to be running to handle any potential print jobs that may be sent to the printer.

Here are some common scenarios where the Spooler SubSystem App process may be running:

  • You have a printer connected to your computer, and the spooler is actively managing print jobs.
  • You recently printed a document, and the spooler is waiting for additional print jobs or managing the printing queue.
  • You have a network printer installed, and the spooler is handling print jobs from other computers on the network.

If you do not have a printer connected to your computer and do not intend to use the printing functionality, you can disable the spooler service to prevent the process from running. However, keep in mind that disabling the spooler will prevent you from printing any documents in the future.

Is the Spooler SubSystem App Process a Security Concern?

The Spooler SubSystem App process itself is not a security concern. It is a legitimate system process that is essential for printing functionality. However, like any other system process, it is possible for malicious software to disguise itself as the spooler process.

If you notice any unusual behavior or suspect that the spooler process may be compromised, it is recommended to scan your computer for viruses and malware. Malwarebytes Free is a reliable antivirus software that can help detect and remove any potential threats.

Troubleshooting Common Spooler SubSystem App Issues

While the Spooler SubSystem App process is generally reliable, there are instances where it may encounter issues. Here are some common problems associated with the spooler process and their potential solutions:

Print Jobs Stuck in the Queue

If you have print jobs stuck in the queue and they are not being processed or printed, you can try the following steps:

  1. Open the Services window by pressing Windows Key + R and typing services.msc.
  2. Locate the “Print Spooler” service, right-click on it, and select Restart.
  3. Wait for the service to restart and check if the print jobs are now being processed.

Print Spooler Service Not Running

If you receive an error message stating that the print spooler service is not running, you can try the following steps:

  1. Open the Services window by pressing Windows Key + R and typing services.msc.
  2. Locate the “Print Spooler” service, right-click on it, and select Properties.
  3. In the Properties window, ensure that the Startup type is set to Automatic. If it is set to Manual or Disabled, change it to Automatic.
  4. Click on the Start button to start the service.
  5. Click Apply and OK to save the changes.

Summary

The Spooler SubSystem App process, spoolsv.exe, is an integral part of the Windows operating system that handles print jobs and manages the printing queue. It ensures that print jobs are processed efficiently and sent to the correct printer. The process is always running in the background to handle any potential print jobs, even if you are not actively printing anything.

While the spooler process itself is not a security concern, it is important to remain vigilant and scan your computer for viruses and malware if you suspect any unusual behavior. Malwarebytes Free is a reliable antivirus software that can help detect and remove any potential threats.

If you encounter any issues with the spooler process, such as print jobs stuck in the queue or the print spooler service not running, you can try troubleshooting steps like restarting the service or ensuring the startup type is set to automatic.

Understanding the Spooler SubSystem App process and its role in the printing functionality of your computer can help you troubleshoot any issues that may arise and ensure a smooth printing experience.

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. Use a good antivirus and keep it up-to-date.

    Shield Guide

    It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

  2. Keep software and operating systems up-to-date.

    updates-guide

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    Trojan Horse

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    warning sign

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.

    backup sign

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Choose strong passwords.

    lock sign

    Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

  9. Be careful where you click.

    cursor sign

    Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

  10. Don't use pirated software.

    Shady Guide

    Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
